Hypermetabolic Broad Ligament Leiomyoma in Postmenopausal Women Mimicking Ovarian Tumors on 18 F-FDG PET/CT.

Extrauterine leiomyomas are rare and often occur in broad ligament or fallopian tube. Diagnosis of broad ligament leiomyoma is challenging for its solid nature and special location. Leiomyomas typically exhibit mild FDG uptake, especially in postmenopausal woman. We here reported a 57-year-old postmenopausal woman with intense FDG-avid broad ligament leiomyoma on 18 F-FDG PET/CT, which might be misdiagnosed as ovarian tumor.
